Hi
I just installed a sub-panel in our guest house to handle increased electric usage ( mostly the air con)
Connected the wire between the main shut off and the house panel and ran to sub-panel in the guest house and installed a ground out there
Now the florescent and LED lights in the main house are all "ghost lights" -they always have a glow at night
Also seem to have a really high elect bill now-almost double
Any idea whats causing this and a recommended fix?
